 |

okey..
i'm so damn newbie...
but I just think that this is possible, but still don't know how to build this...
I have two LEDS, green and red.
I wanna control those LEDS using PC connected with serial port (com) and microcontroller.
I need C code that can display two command menus, turn on only green LED and turn on only red LED...
with this simple scenario, I hope I can build more complex scenario in controllong device from PC..
I need list of components( type of microcontroller, resistor, capacitor ) needed to build this..
thanks before... |

Are you apposed to using the parallel port? This could be very easy to do with the parallel port 
If you have to use the serial port and micro-controller then I'd use a PICAXE. You don't need to by a programing board you just need a few parts. |

To attach an LED to the parallel port you need a parallel port cable, a resistor and an LED
FreeBasic code:
| Code: | do while inkey$ = ""
out 888, 0
sleep 1000
out 888, 1
sleep 1000
out 888, 2
sleep 1000
out 888, 3
sleep 1000
loop
|
Heres some more info. on the parallel port. |
